Overview
The TSC2046IRGVRG4 is a resistive touch screen controller manufactured by Texas Instruments. It features a 12-bit analog-to-digital converter with a sampling rate of 125 kS/s. The device operates on a supply voltage range of 2.2 V to 5.25 V and draws 280 µA during operation. It supports Serial, 3-Wire, SPI, and SSI interfaces. The component is housed in a 16-pin VQFN package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- 12-bit resolution with 125 kS/s sampling rate
- Low power consumption of 280 µA operating current
- Supports multiple digital interfaces: SPI, SSI, 3-Wire, and Serial
- Operates on 2.2 V to 5.25 V supply voltage
Applications
- Resistive touch screen control systems
- Portable electronic devices requiring low-power touch input
- Industrial control panels with resistive overlays
Procurement Notes
Verify the G4 suffix indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the VQFN-16 package dimensions against PCB footprint requirements. Check for moisture sensitivity level (MSL) ratings to ensure proper storage and reflow soldering procedures are followed during assembly.
Selection Notes
Select this component when a 12-bit resolution is required for resistive touch applications. Ensure the host microcontroller supports one of the compatible serial interfaces (SPI, SSI, or 3-Wire). Verify that the system power supply falls within the 2.2 V to 5.25 V range to guarantee correct operation.
Part Context
This part belongs to the TSC2046 family of touch screen controllers from Texas Instruments. It is functionally similar to other variants like the TSC2046IPWRG4 but differs in packaging. The G4 suffix typically denotes environmental compliance updates within the product line.
Replacement Considerations
The TSC2046EIRGVRG4 is a documented alternative within the same family. Verify pin compatibility and interface settings before substitution. Other family members like TSC2046IPWRG4 offer different packages but share core electrical characteristics.
